This shouldn't be too hard...I'm thinking you can drill a pilot hole in the middle of the cone and slowly, carefully enlarge it...how depends on the material, I bet it's very thin, I'd try a very sharp exacto or scalpel, that way there won't be any shavings in the VC gap. If you go slowly enough the pressure from the blade shouldn't distort anything...but I'm only guessing at how 'soft' the cone material is.
It doesn't have the HF response of the JX92S or the SPL capability but it does make for a very nice personal speaker. I use them for PC speakers.

I don't believe they are actual aluminum cones in the tradition of Jordan or Bandor, rather they appear to be treated paper very much like the Tangband W3-871S. The coating makes them stiffer while adding little mass which works very well. They don't have the "paper" sound that lesser drivers do.
dave,
Where I work, when we want to remove material without it falling into a hole, we turn the thing hole-side-up and it falls away from the hole. Just a suggestion.
Anyway, is it too thick/ durable to cut with a new scalpel or xacto blade? I guess so if you mention a dremel. Try a low speed with a big toothy bit to scratch out the initial hole, maybe you won't get as many chunks that way. maybe mount it sideways in a vise and use a low-power vacuum to keep the dust out. Don't forget the goggles!

I've got that down... with a dremel some of the bits will likely be given enuff velocity to go away from gravity... the coil hoil is deep enuff that i can jam a foam plug in before operating -- that will also help hold the cone in place.

I was able to carve away an initial hole with a scalpel -- going thru a few blades, but there is not enuff control to get a clean edge near the voice coil. If i'm lucky some of the early FE103 prototype plugs are going to fit.
